IEC 62481-2:2017

Digital living network alliance (DLNA) home networked device interoperability guidelines - Part 2: Media format profiles

IEC 62481-2:2017(E) describes DLNA Media Format Profiles applicable to the DLNA Device Classes defined in IEC 62481-1-1:2017. Media Format Profiles are defined for each of the following Media Classes: Audio, Image, and AV. In addition, Profile ID values that identify media collections are also introduced.
This third edition cancels and replaces the second edition published in 2013, and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) removal of optional media format profiles for Audio and AV content;
b) addition of mandatory media format profiles for the CVP-2 Device Profile;
c) includes updates to resolve interoperability issues.
